What it is

The Altecnic 3/8 F Non-Return Valve is a check valve manufactured by Altecnic for use within boiler systems and check valve assemblies. It permits flow in one direction only, closing automatically to prevent backflow through the pipework. The 3/8 F connection is suited to small-bore pipework and manifold connections where reverse flow must be stopped.

Signs this part needs replacing

  • Water or system fluid passing in the wrong direction through the circuit
  • Persistent backflow at the valve despite correct installation orientation
  • Dripping or weeping from the valve body or connection
  • Scale or debris holding the internal seal open, so the valve no longer closes
  • Reduced or erratic flow through the check valve assembly

Before you order

  • Confirm the connection size and thread type on the existing valve match the 3/8 F fitting
  • Check the flow direction arrow or marking on the valve body against the direction of flow in the pipework
  • Inspect the surrounding pipework and seals for damage or debris before fitting a replacement
  • Verify the valve is suitable for the system pressure and temperature on the appliance
